This application is a National Stage application of InternationalApplication No. PCT/EP2016/051177, filed Jan. 21, 2016. This applicationalso claims priority under 35 U.S.C. § 119 to European PatentApplication No. 15152163.0, filed Jan. 22, 2015.

The present invention relates to a herbicidal combination comprisingsaflufenacil, a herbicide B selected from sulfentrazone, carfentrazone,butafenacil, fomesafen, oxyfluorfen, acifluorfen, lactofen, flumioxazin,clomazone, topramezone, dicamba, 2,4-D, pendimethalin and their saltsand esters and at least one herbicide C different therefrom. Thecombination is particularly useful for preplant burndown.

Burndown, i.e. the complete removal of weeds from the soil byapplication of herbicides prior to planting or emergence of a crop, isan important tool of modern weed management. Weeds present at plantingwill generally grow much quicker than crop plants and thus compete veryearly in the growing season thereby damaging the crop plants andreducing crop yield. Thus, it is desirable to plant the crop in aweed-free seed bed or to assure that essentially no weeds are presentwhen the crop emerges.

Saflufenacil is the common name of the compound2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1-(2H)pyrimidinyl]-4-fluoro-N-[[methyl(1-methylethyl)-amino]sulfonyl]benzamidewhich is a herbicidal active substance from the group of PPO inhibitors.Saflufenacil has been described in WO 01/083459. Further processes forits preparation are described in WO 03/097589, WO 05/054208, WO06/097589, WO 06/125746 and WO 08/043835. Saflufenacil is particularlyuseful for preplant applications and selective preemergence weed controlin multiple crops, including corn and soybean.

Sulfentrazone, carfentrazone, butafenacil, fomesafen, oxyfluorfen,acifluorfen, lactofen, flumioxazin, clomazone, topramezone, dicamba,2,4-D, pendimethalin and their salts and esters are all well-knownherbicides that share common characteristics, such as e.g. a goodacticity against dicotyledonous weeds. In addition, all of theseherbicides have been used in combined applications with at least onesecond herbicide. However, the effectiveness of such combinations isoften not satisfactory and high application rates are still required toachieve an acceptable control of a broad spectrum of weeds. Moreover,the reliability of such combinations depends strongly on the weatheringconditions and certain difficult to control weed species may escape. Inaddition, the herbicidal activity of these compositions often persistsonly for a short time, which allows effective burndown only within asmall timeframe prior to planting a crop. Moreover, the persistence ofthe herbicidal activity strongly depends upon the weathering conditions.

So far only a very few specific herbicidal mixtures that besidessaflufenacil and an additional herbicide selected from sulfentrazone,carfentrazone, butafenacil, fomesafen, oxyfluorfen, acifluorfen,lactofen, flumioxazin, clomazone, topramezone, dicamba, 2,4-D andpendimethalin also include one or more further herbicides have beendisclosed.

WO 2013/134310 relates to herbicidal compositions that besides fomesafenand saflufenacil also comprise a herbicide selected from flufenacet,dimethenamid, acetochlor or metolachlor.

WO 2014/077343 inter alia discloses herbicidal compositions includingpyraflufen-ethyl, saflufenacil and a further herbicide selected fromcarfentrazone-ethyl, sulfentrazone, flumioxazin, fomesafen, acifluorfenand oxyfluorfen.

It is an object of the present invention to provide a herbicidalcombination, which allows efficient and reliable control of grass andbroadleaf weeds in a burndown program. Moreover, the persistence of theherbicidal activity of the combination should be sufficiently long inorder to achieve control of the weeds over a sufficient long time periodthus allowing a more flexible application. The combination should alsohave a low toxicity to humans or other mammals. The combinations shouldalso show an accelerated action on harmful plants, i.e. they shouldeffect damaging of the harmful plants more quickly in comparison withapplication of the individual herbicides.

These and further objects are achieved by the combinations describedhereinafter.

Therefore the present invention relates to a herbicidal combinationcomprising:

a) a herbicide A which is saflufenacil,

b) a single herbicide B selected from sulfentrazone, flumioxazin,dicamba and their salts and esters, and

c) at least one herbicide C different from herbicides A and B which isselected from

-   -   C.1) herbicides of the group of acetolactate synthase        inhibitors,    -   C.2) herbicides of the group of protoporphyrinogen oxidase        inhibitors,    -   C.3) herbicides of the group of synthetic auxins,    -   C.4) herbicides of the group of microtubule inhibitors,    -   C.5) herbicides of the group of acetyl-CoA carboxylase        inhibitors,    -   C.6) herbicides of the group of photosystem II inhibitors,    -   C.7) herbicides of the group of pigment synthesis inhibitors,        and    -   C.8) herbicides of the group of VLCFA inhibitors selected from        chloroacetamide herbicides, oxyacetamide herbicides, acetamide        herbicides and tetrazolinone herbicides,

provided that the herbicidal combination does not include pyroxasulfone,

provided that in case the components b) or c) comprise dicamba or one ofits salts or esters the herbicidal combination does not include imazapyror one of its salts, and provided that if component b) is flumioxazinand component c) is 2,4-D, 2,4-D is present as its 2-ethylhexyl ester.

The invention furthermore relates to the use of a combination as definedherein for controlling undesirable vegetation. When using thecombinations of the invention for this purpose the herbicide A, theherbicide B and the at least one herbicide C can be appliedsimultaneously or in succession, where undesirable vegetation may occur.

The invention furthermore relates to the use of a combination as definedherein for controlling undesirable vegetation for burndown, i.e. forcontrolling undesirable vegetation in a locus, e.g. a field, where cropswill be planted, before planting or emergence of the crop.

The invention furthermore relates to the use of a combination as definedherein for controlling undesirable vegetation in crops which, by geneticengineering or by breeding, are resistant to one or more herbicidesand/or pathogens such as plant-pathogenous fungi, and/or to attack byinsects; preferably resistant to saflufenacil and/or resistant to theone or more herbicides C and/or resistant to one or more herbicides D,as defined below.

The invention furthermore relates to a method for controllingundesirable vegetation, which comprises applying an herbicidalcombination according to the present invention to the undesirablevegetation. Application can be done before, during and/or after,preferably during and/or after, the emergence of the undesirablevegetation. The herbicide A, the herbicide B and the at least oneherbicide C can be applied simultaneously or in succession.

The invention in particular relates to a method for controllingundesirable vegetation in crops, which comprises applying a combinationas defined herein to a locus of planted crops where undesirablevegetation occurs or might occur or to a locus where crops will beplanted before planting or emergence of the crop.

In the methods of the present invention it is immaterial whether theherbicide A, the herbicide B and the one or more herbicides C areformulated jointly or separately and applied jointly or separately, and,in the case of separate application, in which order the applicationtakes place. It is only necessary, that the herbicide A, the herbicide Band the one or more herbicides C are applied in a time frame, whichallows simultaneous action of the active ingredients on the undesirableplants.

The invention also relates to an herbicide formulation, which comprisesa herbicidally active combination as defined herein and at least onecarrier material, including liquid and/or solid carrier materials.

The combinations of the present invention have several advantages oversolo application of either saflufenacil or any one of herbicides B andC, and, likewise, over any binary combination of these herbicides. Thecombination of the present invention show enhanced herbicide action incomparison with the herbicide action of solo action of saflufenacil orany one of herbicides B and C against undesirable vegetation, inparticular against difficult to control species such as Alopecurusmyosuroides, Avena fatua, Bromus spec., Echinocloa spec. Ipomea spec.,Lolium spec., Phalaris spec., Setaria spec., Digitaria spec., Brachiariaspec., Amaranthus spec., Chenopodium spec., Abutilon theophrasti, Galiumaparine, Veronica spec., or Solanum spec. Moreover, the combinations ofthe invention show a persistant herbicidal activity, even underdifficult weathering conditions, which allows a more flexibleapplication in burndown applications and minimizes the risk of weedsescaping. The combinations are generally non-toxic or of low toxicityagainst mammals. Apart form that, the combinations of the presentinvention show superior crop compatibility with certain conventionalcrop plants and with herbicide tolerant crop plants, i.e. their use inthese crops leads to a reduced damage of the crop plants and/or does notresult in increased damage of the crop plants. Thus, the combinations ofthe invention can also be applied after the emergence of the cropplants. The combinations of the present invention may also show anaccelerated action on harmful plants, i.e. they may effect damage of theharmful plants more quickly in comparison with solo or binaryapplications of the at least three herbicides involved.

The combinations of the invention may also comprise one or moresafeners. Safeners, also termed as herbicide safeners are organiccompounds which in some cases lead to better crop plant compatibilitywhen applied jointly with specifically acting herbicides. Some safenersare themselves herbicidally active. In these cases, the safeners act asantidote or antagonist in the crop plants and thus reduce or evenprevent damage to the crop plants. However, in the combinations of thepresent invention, safeners are generally not required. Therefore, apreferred embodiment of the invention relates to combinations whichcontain no safener or virtually no safener (i.e. less than 1% by weight,based on the total amount of herbicide A and herbicide B).

Suitable safeners, which can be used in the combinations according tothe present invention are known in the art, e.g. from

A preferred embodiment of the invention relates to combinations whichcontain no safener or virtually no safener, i.e. less than 1% by weight,based on the total amount of the herbicide B, saflufenacil, the at leastone herbicide C and the optional herbicide D to be applied.

The combinations of the present invention are suitable for controlling alarge number of harmful plants, including monocotyledonous weeds, inparticular annual weeds such as gramineous weeds (grasses) includingEchinochloa species such as barnyardgrass (Echinochloa crusgalli var.crus-galli), Digitaria species such as crabgrass (Digitariasanguinalis), Setaria species such as green foxtail (Setaria viridis)and giant foxtail (Setaria faberii), Sorghum species such asjohnsongrass (Sorghum halepense Pers.), Avena species such as wild oats(Avena fatua), Cenchrus species such as Cenchrus echinatus, Bromusspecies, Lolium species, Phalaris species, Eriochloa species, Panicumspecies, Brachiaria species, annual bluegrass (Poa annua), blackgrass(Alopecurus myosuroides), Aegilops cylindrica, Agropyron repens, Aperaspica-venti, Eleusine indica, Cynodon dactylon and the like.

The combinations of the present invention are also suitable forcontrolling a large number of dicotyledonous weeds, in particular broadleaf weeds including Polygonum species such as wild buckwheat (Polygonumconvolvolus), Amaranthus species such as pigweed (Amaranthusretroflexus), Chenopodium species such as common lambsquarters(Chenopodium album L.), Sida species such as prickly sida (Sida spinosaL.), Ambrosia species such as common ragweed (Ambrosia artemisiifolia),Acanthospermum species, Anthemis species, Atriplex species, Cirsiumspecies, Convolvulus species, Conyza species, Cassia species, Commelinaspecies, Datura species, Euphorbia species, Geranium species, Galinsogaspecies, morningglory (Ipomoea species), Lamium species, Malva species,Matricaria species, Sysimbrium species, Solanum species, Xanthiumspecies, Veronica species, Viola species, common chickweed (Stellariamedia), velvetleaf (Abutilon theophrasti), Hemp sesbania (Sesbaniaexaltata Cory), Anoda cristata, Bidens pilosa, Brassica kaber, Capsellabursa-pastoris, Centaurea cyanus, Galeopsis tetrahit, Galium aparine,Helianthus annuus, Desmodium tortuosum, Kochia scoparia, Mercurialisannua, Myosotis arvensis, Papaver rhoeas, Raphanus raphanistrum, Salsolakali, Sinapis arvensis, Sonchus arvensis, Thlaspi arvense, Tagetesminuta, Richardia brasiliensis, and the like.

Therefore, the present invention also relates to a method forcontrolling undesirable vegetation, comprising applying a herbicidalcombination according to the present invention, i.e. a herbicidalcombination comprising:

-   -   a) saflufenacil,    -   b) a single herbicide B or one of its salts,    -   c) at least one herbicide C as defined above, and    -   d) optionally at least one further herbicide D as defined above,        to a locus where undesirable vegetation is present or is        expected to be present.

The combinations of the present invention are particularly useful inso-called burndown programs, in particular preplant burndown programs.i.e. the combinations of the invention are applied to a locus wherecrops will be planted before planting or emergence of the crop.

Therefore, the present invention also relates to a method for burndowntreatment of undesirable vegetation in crops, comprising applying aherbicidal combination according to the present invention, i.e. aherbicidal combination comprising:

-   -   a) saflufenacil,    -   b) single herbicide B or one of its salts,    -   c) at least one herbicide C as defined above, and    -   d) optionally at least one further herbicide D as defined above,

to a locus where crops will be planted before planting or emergence ofthe crop.

In the burndown treatment of the present invention, additionally atleast one further herbicide D as defined above can be applied togetherwith the herbicides A, B and C. The term “to apply together” includessimultaneous and successive application. Likewise, applying thecomposition does not necessarily mean that the compounds A, B, C andoptionally D must be applied as a single formulation or as a tank mix.Rather, the combination includes separate formulations of herbicides A,B and C and optionally D, which can be applied as a single tank-mix orvia separate application means. In any case, the herbicide A, theherbicide B, the at least one herbicide C and the one or more optionalherbicides D can be applied simultaneously or in succession.

However, it is also possible to apply the herbicides C and D in theburndown treatment after seeding or even after emergence of the crop.

Though possible, it is not necessary to formulate the herbicides A, B, Cand optionally D in a single formulation. Usually the herbicides A, B, Cand optionally D are combined as a tank-mix prior to application. It ishowever also possible to provide a premix of the herbicides A and C andthe optional herbicide D and to combine this premix with the herbicideB.

The combinations of the present invention can be applied in conventionalmanner by using techniques as skilled person is familiar with. Suitabletechniques include spraying, atomizing, dusting, spreading or watering.The type of application depends on the intended purpose in a well knownmanner; in any case, they should ensure the finest possible distributionof the active ingredients according to the invention.

The combinations are applied to locus mainly by spraying, in particularfoliar spraying of an aqueous dilution of the active ingredients of thecombination. Application can be carried out by customary sprayingtechniques using, for example, water as carrier and spray liquor ratesof from about 10 to 2000 I/ha or 50 to 1000 I/ha (for example from 100to 500 I/ha). Application of the herbicidal combinations by thelow-volume and the ultra-low-volume method is possible, as is theirapplication in the form of microgranules.

If the active ingredients are less well tolerated by certain cropplants, application techniques may be used in which the herbicidalcombinations are sprayed, with the aid of the spray apparatus, in such away that they come into as little contact, if any, with the leaves ofthe sensitive crop plants while reaching the leaves of undesirableplants which grow underneath, or the bare soil (post-directed, lay-by).

The combinations can be applied pre- or post-emergence, i.e. before,during and/or after emergence of the undesirable plants.

When the combinations are used in burndown programs, they can be appliedprior to seeding (planting) or after seeding (or planting) of the cropplants but before the emergence of the crop plants. The combinations arepreferably applied prior to seeding of the crop plants. For burndown,the combinations will generally be applied at a date up to 9 month,frequently up to 6 month, preferably up to 4 month prior to planting thecrop. The burndown application can be done at a date up to 1 day priorto emergence of the crop plant and is preferably done at a date prior toseeding/planting of the crop plant, preferably at a date of at least oneday, preferably at least 2 days and in particular at least one 4 daysprior to planting or from 6 month to 1 day prior emergence, inparticular from 4 month to 2 days prior emergence and more preferablyfrom 4 month to 4 days prior emergence. It is, of course, possible torepeat the burndown application once or more, e.g. once, twice, threetimes, four times or five times within that time frame.

In the burndown treatment according to the present invention, theherbicide A, the herbicide B and the at least one herbicide C areapplied to the field of the crop plants prior to the emergence of thecrop plants, in particular prior to seeding within the above time frame.In a specific embodiment of this burndown treatment, the one or moreherbicides D are also applied within this time frame. In this specificembodiment it is also possible to additionally apply the one or moreherbicides D and optionally additional amounts of saflufenacil and/orthe at least one herbicide C after the planting or seeding or even afteremergence of the crop, preferably at a date until 12 weeks afteremergence of the crop. In another specific embodiment of this burndowntreatment, the one or more herbicides D and the optional additionalamounts of saflufenacil and the at least one herbicide C are onlyapplied after the planting or seeding or even after emergence of thecrop, preferably at a date until 12 weeks after emergence of the crop.

It is a particular benefit of the combinations according to theinvention that they have a very good post-emergence herbicide activity,i.e. they show a good herbicidal activity against emerged undesirableplants. Thus, in a preferred embodiment of the invention, thecombinations are applied post-emergence, i.e. during and/or after, theemergence of the undesirable plants. It is particularly advantageous toapply the mixtures according to the invention post-emergent when theundesirable plant starts with leaf development up to flowering. Thecombinations are particularly useful for controlling undesirablevegetation which has already developed to a state, which is difficult tocontrol with conventional burndown combinations, i.e. when theindividual weed is taller than 10 cm (4 inches) or even taller than 15cm (6 inches) and/or for heavy weed populations.

In the case of a post-emergence treatment of the plants, the herbicidalmixtures or combinations according to the invention are preferablyapplied by foliar application.

Application may be effected, for example, by usual spraying techniqueswith water as the carrier, using amounts of spray mixture of usuallyfrom 10 to 2000 I/ha, in particular 50 to 1000 I/ha.

The required application rate of the combination of the pure activecompounds, i.e. of saflufenacil, herbicide B, at least one herbicide Cand optionally herbicide D depends on the density of the undesiredvegetation, on the development stage of the plants, on the climaticconditions of the location where the combination is used and on theapplication method. In general, the application rate of the combination(total amount of herbicides A, B, C and optional further actives) isfrom 55 to 6000 g/ha, preferably from 100 to 5000 g/ha, from 200 to 4000g/ha, and more preferably from 300 to 3000 g/ha of active ingredient(a.i.).

The application rates of the herbicide C.3 (total amount of herbicideC.3) are generally in the range from 10 g/ha to 8000 g/ha and preferablyin the range from 20 g/ha to 6000 g/ha or from 100 g/ha to 4000 g/ha ofactive substance.

The application rates of the herbicide C.4 (total amount of herbicideC.4) are generally in the range from 10 g/ha to 8000 g/ha and preferablyin the range from 20 g/ha to 6000 g/ha or from 40 g/ha to 4000 g/ha ofactive substance.

The application rates of the herbicide C.5 (total amount of herbicideC.5) are generally in the range from 1 g/ha to 2000 g/ha and preferablyin the range from 2 g/ha to 1000 g/ha or from 5 g/ha to 750 g/ha ofactive substance.

The required application rates of the herbicide C.6 (total amount ofherbicide C.6) are generally in the range from 10 g/ha to 8000 g/ha andpreferably in the range from 20 g/ha to 6000 g/ha or from 50 g/ha to4000 g/ha of active substance.

The application rates of the herbicide C.7 (total amount of herbicideC.7) are generally in the range from 1 g/ha to 3000 g/ha and preferablyin the range from 5 g/ha to 2000 g/ha or from 10 g/ha to 1000 g/ha ofactive substance.

If not stated otherwise, the combinations of the invention are suitablefor application in fields of any variety of the aforementioned cropplants.

The combinations according to the invention can also be used in cropplants which are resistant to one or more herbicides owing to geneticengineering or breeding, which are resistant to one or more pathogenssuch as plant pathogenous fungi owing to genetic engineering orbreeding, or which are resistant to attack by insects owing to geneticengineering or breeding. Suitable are for example crop plants,preferably corn, wheat, sunflower, rice, canola, oilseed rape, soybeans,cotton and sugarcane, which are resistant or tolerant to any one ofherbicides B, crop plants which are resistant or tolerant to syntheticauxins such as dicamba, crop plants which are resistant or tolerant toHPPD inhibitors, crop plants which are resistant or tolerant to ALSinhibitors such as imidazolinone herbicides, crop plants which areresistant or tolerant to PPO inhibitors or crop plants which, owing tointroduction of the gene for Bt toxin by genetic modification, areresistant to attack by certain insects.

In a particular a specific embodiment, the combinations of the presentinventions are used for controlling undesirable vegetation to cropplants, which are tolerant to herbicides, in particular in crop plantsthat are resistant or tolerant to any one of herbicides B and which arestacked with further resistance or tolerance against at least onefurther herbicide, in particular at least one of the followingherbicides: synthetic auxins such as dicamba, HPPD inhibitors, ALSinhibitors such as imidazolinone herbicides, PPO inhibitors.

In these herbicide resistant or tolerant crops, the combinations of thepresent invention can be used both for burndown and for control ofundesired vegetation after emergence of the crops. Therefore, aparticular embodiment of the invention relates to a method forcontrolling undesirable vegetation in herbicide resistant or tolerantcrops, in particular in crop plants which are resistant or tolerant toany one of herbicides B and which are optionally stacked with furtherresistance or tolerance against at least one further herbicide, inparticular at least one of the following herbicides: synthetic auxinssuch as dicamba, HPPD inhibitors, ALS inhibitors such as imidazolinoneherbicides, PPO inhibitors. In this particular embodiment, thecombinations can be used for burndown but also for the control ofundesirable vegetation after emergence of the crop plants.

In this particular method of the invention, the combination of theinvention can be applied at least once prior to planting or emergence ofthe herbicide resistant or tolerant crop plants to achieve effectiveburndown of the undesirable vegetation and the combination can also beapplied after emergence of the herbicide resistant or tolerant cropplants.

If the combinations of the present invention are used in crop plants,i.e. if they are applied in fields of the crop plants after emergence ofthe crops, application methods and application rates as described forburndown can be applied. If the active ingredients are less welltolerated by certain crop plants, application techniques may be used inwhich the herbicidal combinations are sprayed, with the aid of the sprayapparatus, in such a way that they come into as little contact, if any,with the leaves of the sensitive crop plants as possible while reachingthe leaves of undesirable plants which grow underneath, or the bare soil(post-directed, lay-by). However, such methods are generally notnecessary and the combinations can be simply applied over the top (OTT).

For example, a combination comprising sulfentrazone, saflufenacil and asynthetic auxin herbicide is particularly useful for burndown in fieldsboth of conventional crops such as maize, canola, wheat, soybeans,sunflower and sugarcane and crops having sulfentrazone tolerance,optionally stacked with synthetic auxin tolerance. This combination canalso be used for controlling undesirable vegetation in crops havingsulfentrazone tolerance optionally stacked with synthetic auxinresistance after emergence of the crop.

For example, a combination comprising sulfentrazone, saflufenacil and anALS inhibitor herbicide is particularly useful for burndown in fieldsboth of conventional crops such as maize, wheat, soybeans, sunflower andsugarcane and crops having sulfentrazone tolerance, optionally stackedwith further herbicide tolerance. This combination can also be used forcontrolling undesirable vegetation in such crops after emergence of thecrop.

For example, a combination comprising sulfentrazone, saflufenacil and aPPO inhibitor herbicide is particularly useful for burndown in fieldsboth of conventional crops such as maize, wheat, soybeans, sunflower andsugarcane and crops having sulfentrazone tolerance, optionally stackedwith PPO inhibitor tolerance. This combination can also be used forcontrolling undesirable vegetation in such crops after emergence of thecrop.

For example, a combination comprising sulfentrazone, saflufenacil and amicrotubule inhibitor herbicide is particularly useful for burndown infields both of conventional crops such as maize, wheat, soybeans,sunflower and sugarcane and crops having sulfentrazone tolerance,optionally stacked with further herbicide tolerance. This combinationcan also be used for controlling undesirable vegetation in such cropsafter emergence of the crop.

For example, a combination comprising sulfentrazone, saflufenacil and aHPPD inhibitor herbicide is particularly useful for burndown in fieldsboth of conventional crops of small grain cereals and crops of smallgrain cereals having sulfentrazone tolerance, optionally stacked withfurther herbicide tolerance. This combination can also be used forcontrolling undesirable vegetation in such crops after emergence of thecrop.

For example, a combination comprising sulfentrazone, saflufenacil and aPS II inhibitor herbicide of the group C.6.2 or C.6.3 is particularlyuseful for burndown in fields both of conventional crops of maize orsugarcane and crops of maize or sugarcane having sulfentrazonetolerance, optionally stacked with further herbicide tolerance. Thiscombination can also be used for controlling undesirable vegetation insuch crops after emergence of the crop.

For example, a combination comprising sulfentrazone, saflufenacil and anACC inhibitor herbicide is particularly useful for burndown in fieldsboth of conventional crops such as maize, wheat, soybeans, sunflower andsugarcane and crops having sulfentrazone tolerance, optionally stackedwith further herbicide tolerance. This combination can also be used forcontrolling undesirable vegetation in such crops after emergence of thecrop.

For example, a combination comprising sulfentrazone, saflufenacil and aVLCFA inhibitor herbicide is particularly useful for burndown in fieldsboth of conventional crops of small grain cereals, maize, soybean,sunflower or sugarcane and crops of small grain cereals, maize, soybean,sunflower or sugarcane having sulfentrazone tolerance, optionallystacked with further herbicide tolerance. This combination can also beused for controlling undesirable vegetation in such crops afteremergence of the crop.

USE EXAMPLES

The effect of the herbicidal combinations according to the invention ofherbicides A, B and C and, if appropriate, safener on the growth ofundesirable plants compared to the herbicidally active compounds aloneor binary mixtures thereof was demonstrated by the following greenhouseexperiments:

The test plants were first grown to a height of 3 to 20 cm, depending onthe plant habit, and only then treated (post-emergence treatment). Here,the herbicidal combinations were suspended, emulsified or dissolved inwater as distribution medium and afterwards applied by spraying, usingfinely distributing nozzles.

The herbicides A, B and C were used as commercially availableformulations and introduced to the spray liquor with the amount ofsolvent system used for applying the active compound. In the examples,the solvent used was water.

The test period extended over 20 days. During this time, the plants weretended, and their response to the treatments with active compounds wasevaluated.

The evaluation for the damage caused by the chemical compositions wascarried out using a scale from 0 to 100%, compared to the untreatedcontrol plants. Here, 0 means no damage and 100 means completedestruction of the plants.

The plants used in the greenhouse experiments belonged to the followingspecies:

Scientific Name Code Common Name Abutilon theophrasti ABUTH velvetleafAmaranthus retroflexus AMARE pig weed Avena fatua AVEFA wild oatBrachiaria decumbens BRADC Surinam grass Brachiaria platyphylla BRAPPbroadleaf signalgrass Digitaria sanguinalis DIGSA large crabgrassEchinochloa crus-galli ECHCG barnyardgrass Setaria viridis SETVI greenfoxtail Solarium nigrum SOLNI black nightshade

Colby's formula was applied to determine whether the composition showedsynergistic action. The value E, which is to be expected if the activityof the individual compounds is just additive, was calculated using themethod of S. R. Colby (1967) “Calculating synergistic and antagonisticresponses of herbicide combinations”, Weeds 15, p. 22 ff. For twocomponent mixtures the value E was calculated by the following formulaE=X+Y−(X·Y/100)

where X=effect in percent using a mixture of herbicides A and B atapplication rates a and b, respectively;

-   -   Y=effect in percent using herbicide C at an application rate c;    -   E=expected effect (in %) of A+B+C at application rates a+b+c.

If the value observed in this manner is higher than the value Ecalculated according to Colby, a synergistic effect is present.

Tables 1 to 41 relate to the herbicidal activities of the binary mixtureof herbicides A and B, of herbicide C individually and of theircombinations in post-emergence applications assessed 20 days aftertreatment (20 DAT).
